Steel corrugated pipe culverts are used in railway, highway, municipal and other road projects, as well as in the reinforcement of old bridges and culverts, construction of urban common ditches, tunnels, box culverts, seepage wells, coal mine tunnels and other projects. The new type of box culvert structure is used instead of conventional concrete structures. The new box culvert structure uses corrugated plates with flat curvature to increase compressive strength, and can be used in conjunction with channel steel and I-shaped steel pipe materials. It has the characteristics of high safety, good sealing, high bearing capacity, and wide adaptability to the environment. At the same time, adopting a modular connection method makes construction simple and fast, with low requirements for installation work surfaces, and to a certain extent reduces the impact on the environment.

The reinforced corrugated plate box culvert structure includes multiple splicing units, and the multi-faceted splicing units are vertically connected through connecting pieces to form a closed box culvert structure, including upper, lower, left, and right splicing units. The splicing units include steel corrugated plates, reinforcement pipes, and fixed transverse plates. The reinforcement pipes are set in the valleys of the steel corrugated plates, and the reinforcement pipes on adjacent splicing units are vertically in contact with each other. All reinforcement pipes form the inner reinforcement frame of the box culvert shape, and several fixed transverse plates are horizontally fixed on the inner wall of the steel corrugated plate to fix the reinforcement pipes.
